So my jeep was running rough, 03 4.7 130 k on it and I was thinking maybe it was just a bad batch of gas because I just filled up this morning then it got worse and now I'm throwing a p0302 cylinder 2 misfire idk what to do my plugs are recent maybe 10 k ago replaces with champion platinum I believe.. And advice? Do you think that it could be a bad tank of gas?

Double check your plug to make sure it's not fouled. Swap the #2 coil with a coil from another cylinder. Clear your codes. If the code jumps to the cylinder you swapped coils with, your coil could be bad.
